ANALOG DEVICES LTC4376IDHD#PBF Ideal Diode Controller, Reverse Input Protection, 7 A, 4 to 40 V, -40 to 85 Deg C, DFN-16

LTC4376 is a 7A ideal diode that uses an internal 15Mohm N-channel MOSFET to replace a schottky diode when used in diode-OR and high current diode applications. It reduces power consumption, heat dissipation and PC board area. It controls the forward voltage drop across the internal MOSFET to ensure smooth current delivery without oscillation even at light loads. If a power source fails or is shorted, a fast turn-off minimizes reverse current transients. It also easily ORs power sources to increase total system reliability. With its low operating voltage, small solution size and the ability to withstand reverse input voltage, this device excels in portable battery applications. The SHDN pin can also control the forward current path when an external MOSFET is used in series with the internal MOSFET in a back-to-back configuration. It is used in application like automotive battery protection, redundant power supplies, portable battery devices, computer systems/servers etc.
